Power® Enterprise Pools provides flexibility and value for Power Systems™. A Power Enterprise Pool is a group of 9119-FHB systems that can share Mobile Capacity on Demand (CoD) processor resources and memory resources.
You can move Mobile CoD resource activations among the systems in a pool with Hardware Management Console (HMC) commands. These operations provide flexibility when you manage large workloads in a pool of systems and helps to rebalance the resources to respond to business needs. This feature is useful for providing continuous application availability during maintenance. Not only can the workloads be easily moved to alternate systems but the processor activations and memory activations can be moved. Disaster recovery planning also is more manageable with the ability to move activations where and when they are required.
All the systems in a pool must be managed by the same HMC or by the same pair of redundant HMCs. If redundant HMCs are used, the HMCs must be connected to a network so that they can communicate with each other. The HMCs must be at V7R7.8 or later and have at least 2 GB of memory.
An HMC can manage multiple Power Enterprise Pools and can also manage systems that are not part of a Power Enterprise Pool. The maximum number of systems an HMC can manage is 32 high-end systems, 48 mid-range, or 48 low-end systems. An HMC can manage a maximum of 1000 total partitions. Systems can belong to only one Power Enterprise Pool at a time.
